Hi, how are you?
I need your help related with nonlineal parameter calculation. I need to undestand how dos Origin calculate the shi square and R square parameter when the lineal adjust is done. When i make these i get thouse values, but when i try tu calculate them from equations that i had found in books, they have not the same value.

i would appreciate you send me your request to the email:
